dmaengine: add dmaengine_is_*_aligned() helpers for DMA consumers
DMA engine consumers typically hold a struct dma_chan pointer and should
not need to reach into struct dma_device directly to check alignment
requirements. Add dmaengine_is_copy_aligned(), dmaengine_is_xor_aligned(),
dmaengine_is_pq_aligned() and dmaengine_is_fill_aligned() as channel-based
counterparts to the existing is_dma_*_aligned() family.
Each wrapper calls dmaengine_check_align() directly with the alignment
value from chan->device, keeping struct dma_device opaque to consumers.
